CLOSURE FOR RENDERING BOTTLES ANTIREFILLABLE.

Specification of Letters Patent.

Patented Jan. 19, 1915.

Application filed January 12, 1914. Serial No. 811,673.

To all whom it may concern:

Be it known that We, ALFRED HENRY LUFF and HENRY CARSON, lVILLMoTT, subjects of the King of Great Britain and Ireland, and

' residents, respectively, of Talbotville, Payneham Road, Payneham, State of South Australia, Commonwealth of Australia, and No. 167 Payneham Road, St. Peters, State of South Australia aforesaid, have invented a certain new and useful Improved Closure for Rendering Bottles Antirefillable, of which the following is a specification.

Our invention has been designed to provide an improved stopper attachment for bottles and other receptacles for" holding spirits or other liquids, for the purpose of preventing the fraudulent refilling, either partial or complete, of such bottles and receptacles, and it relates in particular to an improvement for stoppers designed for use with ordinary bottles having the inside of the neck plain without any special shoulder or seating to retain the stopper. In this 7 specification the word bottle is intended to cover not only glass bottles, but other liq uid containing receptacles such as jars, flagons and the like.

In order that our invention may be clearly understood we will describe the same with reference to the accompanying drawings in which Figure 1 is an outside view of the top of a bottle with our stopper attachment thereon. Fig. 2 is an outside view of our stopper attachment before insertion and affixing to the bottle. Fig. 3 is a sectional view representing the bottle standing upright and before it has been opened. Fig. 4 is a sectional view representing the bottle opened and tilted to discharge contents or portion of same.

Our invention comprises an outer casing A of frusto-cone shape having a perforated inner cylinder B united at one end to the smaller end of the casing A. These two parts may be made separately and then joined together, or they may be formed of one piece. The lower larger end of the conical outer casing A fits upon the top of the neck of the bottle with a resilient washer C interposed to insure tightness, and is attached by rolling a ring of suitable metal or material D similar to a capsule around the adjacent parts of the stopper and of the bottle neck. The lower end of the conical outer casing maybe extended to form the capsule .D so that a single article only has to be handled when attaching the stopper to the bottle; in which case the casing is formedwith an internal flange to fit upon the top of the neck of the bottle.

The perforated inner cylinder B projects into the neck of the bottle. It has at its lower end an external ring E of cork or other resilient material to fit tightly within the neck of the bottle, and also at its lower non-secured end an internal flange G forming a valve seat which is engaged by a valve F, when the bottle is substantially upright. The portion which is covered by the ring E is not perforated. Across the middle of the perforated portion of the cylinder is a solid unperforated disk H. forming a plug above the valve. The upper end of the cylinder is closed, for purposes of carriage, by means of an ordinary cork K or other stopper of any desired material or pattern.

Our attachment may be made of different sizes to suit different sizes and patterns of bottles, and of any material that will not affect or be affected by the contents of the bottle, but preferably it is made of aluininium.

In use, the bottle is filled, and the cork K is inserted in the upper end of the cylinder B before our attachment is secured to the bottle. The attachment is then placed in position with the washer C and washer E and secured to the bottle by rolling or otherwise pressing the capsule D around the adjacent parts of the attachment and of the bottle.

To discharge the contents of the bottle into a glass, the cork K is withdrawn from the cylinder B, and upon the bottle being tilted the valve F leaves its seat and permits the liquid to flow through the flange opening into that portion of the perforated cylinder below the disk or plug I-I, thence it flows through the perforations in the cylinder into the space between the cylinder B and the outer casing A, thence through the perforations into the upper portion of the cylinder and thence into the glass. The frustocone shaped outer casing A provides a space of ample size for the liquid to pass out and the air to pass in, insuring supply of air necessary to take the place of the outflowing liquid and so insuring a free and regular flow of the liquid. The pouring of the liquid into the bottle is prevented by the valve F, and any attempt to lift the valve is prevented by the solid disk or plug H across the center of the cylinder.

What we claim is An improved stopper attachment for bottles and other receptacles comprising an outer casing of frusto-cone shape, the lower and larger end of such casing fitting upon the top of the bottle neck, a capsule or ring securing said casing to the bottle neck a resilient washer interposed between the easing and the top of the bottle neck, a perforated inner cylinder united at its upper end to the upper and smaller end of said casing, the lower portion of the said cylinder projecting into the bottle neck, an external resilient ring upon the lower end of the said cylinder fitting tightly within the bottle neck, an internal flange at the lower end of said cylinder forming a valve seat, a ball.

valve within said cylinder engaging said valve seat, an unperforated disk at about the center of said cylinder separating it into two parts whereby when the bottle is tilted and the ball valve leaves its seat, the liquid from the bottle is first caused to pass through the valve seat into the cylinder, then through the perforations into the bottle neck and the frusto-conical casing, and

thence through the perforations into, and
